ATTACHMENT FOR EYEBOLT-MACHINES.

SPECIFICATION forming part of Letters Patent No. 498,766, dated June 6, 1893.

Application filed October 28, 1892.

To all whom it may concern.-

Be it known that we, CHARLES OoLHowER and ADAM J. GROSSMANN, of Dayton, count-y of Montgomery, State of Ohio, have invented a new and useful Improvement in Attachments for Eyebolt-Machines, of which the following is a specification.

This invention relates to improvements in attachments for eye-bolt machines.

The object of our invention is to provide means for forming an eye accurately, and at the same instant, link the said eye to an eye previously formed.

It is well known, that the production of the eye bolt, at the present time, is either entirely or partially confined to muscular force; where the latter is the case, the eye-bolt alone, is formed by a power machine:linking them, is done in the old n1anner,i. 2., by hand.

For a description of our improvement, the accompanying drawings are referred to.

Figure 1- is a detached, detail view, in perspective, of our improved eye-bending attachment; Fig.2, a plan view of the die; Fig. 3, a side elevation of the same; Fig. 4, a longitudinal transverse section of the same, the pin and an eye-bolt inserted in the recesses in the die and pin; Fig. 5, a plan view of the recessed end of the pin, removed from the die; Fig. 6, a side elevation of the pin, partly in section, and removed from the die; Fig. 7, a detached sectional view of the same, from the rear end. Fig. 8. is a side elevation of an eye bolt machine showing the power wheel, and

the location of the eye bending device. Fig. 9. is an enlarged view with the upper and lower portions of the machine broken away, preparatory to the bolt being formed into and linked with an eye bolt; Fig. 10. a similar view to Fig. 9, showing the completion of the operation and the position of the dog thereafter. Fig. 11. is a view of two eye bolts formed and linked together by means of our improved attachment.

Coming now to a more specificreference, the drawings are lettered, and the same letter will denote identical parts throughout.

The letter A, represents the side of a machine for bending eye-bolts, upon which our improvement is located; power is transmitted thereto by the usual belt, friction clutch, pulley and treadles, and it is thought for the Serial No. 450,295. (No model.)

purposes of an illustration of our attachment, unnecessary to embody any of the well known features of the machine, beyond those imlnediately adjacent to the improved attachment.

B, indicates a disk adapted by means of gearing to rotate almost to a complete circle in the direction of the arrow.

(1)) is a dog, rigidly attached,in an inclined 6c position, to the outer face of the disk.

D; is a die, inclosed in a sleeve D in the center of the disk, and remains stationary while the disk rotates. The essence of our improvement lies in the construction of this die and the pin to be inserted therein, and it is our desire to cover the same by a substantial claim. The die is provided with a longitudinal opening a little off the center, terminating in a channel (e) at right angles to the periphery of the die, as is well illustrated in Fig. 3. The object of this channel is to admit of the insertion of the eye of a bolt ((1) to a desirable depth, for a purpose to be here inafter mentioned. The opening through the 7 5 die is adapted to receive the pin (0) which pin is subjected to a horizontally reciprocating movement; this pin is recessed in a manner eccentric to the circular form thereof, and to a comparative depth to that shown in Fig. 4. The object of the recess in the pin and also the recess in the die, is as before stated to allow the eye of bolt (a) to be inserted therein a sufficient depth to bring the eye at right angles to, and on a horizontal plane with the 5 rod (q) affording it (the rod q) an opportunity to pass through the said eye. The eye is formed by bringing the end of the rod (q) around and over the projecting part of the pin (0) in a manner to be presently explained. It will be understood that the pin and the die are not subjected to the rotatory motion that is imparted to the disk. The pin, however, as previously stated is adapted to a horizontal movement back and forth by which an eye is formed and linked to another and instantly released from the pin by the said pin sliding into the die in a manner to bring its recessed part entirely within said die.

We will endeavor to describe the operation of our attachment and thereby complete the description of our invention. The rod (q) having been subjected to the required heat is by the hand guided horizontally through IOO the vertical slot in the upright dog or support P, and passed through the eye of bolt (0.) as shown in Fig. 8.,the eye-bolt having been simultaneously placed in the recesses of the pin and die respectively. The gage R, limits the distance of the rod (q) as shown in Fig. 8. At this juncture, the disk B, rotates in the direction of the arrow, carrying the dog, I), therewith, and the end of the rod (q) over and around the pin (0) until the circle of the eye is made, when the disk rotates backwardly to its former position. By pressing the treadle of the machine (which hasnot been shownin the drawings, as it is a Well known accompaniment of the eye-bolt machine) the dog P, moves vertically, carriesthe rod therewith and completes the eye by bending the red as shown at (s). The action of the treadle transmits, simultaneously, the power to the disk B, and dog P, and the initial bend (s) is effected at the same moment the rod is formed into the eye.

Having described our invention, What we claim as new, and desire to secure by Letters Patent, is-

1. In an eye-bolt machine, the combination with a rotatory disk and a dog attached to the face thereof, of a die adapted to be sleeved therein, said die provided with a longitudinal opening therethrough, and a channel on the end extending from the center to the periphery of said die, a pin having a recess in one end, the channel in the die and recess in the pin, adapted to receive the eye of a bolt placed endwise therein, substantially as herein described.

2. In an eye-bolt machine, the combination with the disk 13, and the die D, provided with a channel in one end thereof extending from near the center to the circumference, and the pin, having a recess in an end thereof eccentric to the circumferential form of said pin, substantially as described.

3. The'herein described attachment for eyebolt machines, consisting of a die having a longitudinal opening and a channel at right angles to said opening, extending to the periphery of the die, and a pin provided with a recessed end, said pin adapted to enter the longitudinal opening, substantially as herein set forth.

4. The attachment herein described, consisting of the die D, having a longitudinal opening therethrough, and the channel (6) and the pin (0) as herein described.

In testimony whereof we have hereunto set our hands this 11th day of October, 1892.
